For me the most important

thing with in ear monitors

is that the sound is natural.

As long as I hear it the

way it was intended

without a boost of bass or highs. The ES5's are the most incredible in ears I have ever used and provide exactly that. Having 5 drivers (1 low 2 mid 2 high) makes a huge difference. I also use the earplugs with the 15 and 25 decibel filters. For use on my phone or listening to music on the go I use the ts1 (now the Westone Adventure series). Using these products will greatly enhance your listening experience in any situation.
